Om – often referred to as the hymn of the universe – is considered the ultimate vibration because it contains every vibration that has ever existed and every vibration that will ever exist. It’s pure yoga – union. Just as white light contains all the colours of the spectrum, Om contains every sound in the vibrational spectrum – even those we can’t hear with our ears. The cover of Pink Floyd’s Dark Side of the Moon represents this brilliantly as it shows the white light coming into a prism and all the colours of the spectrum coming out the other side. The same could be said for Om – it’s the white light of sound.
Historically, Ohm is first mentioned in the twelve verses of the ancient Vedic text the Mandukya Upanishads, which explains the three basic states of consciousness: waking, sleeping, and dreaming. In its original spelling and pronunciation, AUM (pronounced ahh-uhh-mmm) is a blending of those three states of consciousness into the one-ness of three distinct syllables: A, U, and M. These three vibrations also represent the three stages of life: birth, living, and death.
The vibration A (pronounced ahh, like the sound you make opening your mouth for the doctor) represents the waking state and the beginning of all things. The letter A is the first letter of most every alphabet, the first letter of the Rig Veda, the Koran, Homer’s Odyssey – even the New Testament! The vibration A heralds creation…the beginning. Vedic sages refer to it as the a-kara and it represents the realm of form and shape – the physical realm.
The vibration U (pronounced oo) is referred to as the u-kara and represents the dream state, the realm that is devoid of form or shape – the realms of air, water, fire, dreams – ever-changing aspects of the formless world around us.
The vibration M is known as the ma-kara, which represents the state of deep sleep – neither form or formless like the other two realms but beyond shape or shapelessness – the realm of consciousness in hibernation, waiting to unfold.
In Sanskrit grammar, when the letters A and U are combined in writing, they are translated as the letter O. That is why we so often see Om written instead of Aum. Over thousands of years, the writing of Aum has taken a back seat to Om, and that has led to Om being the sound that is most often chanted by both Western students and teachers of yoga, meditation, and Vedanta.
When the three individual vibrations are combined, a fourth vibration is created like a chord in music made up of individual notes. AUM (pronounced ahhh–uhhh–mmmm) represents the fourth state of consciousness – transcendent consciousness or turiya – what we call enlightenment or one-ness. In Vedanta, it’s the unity of the divine made up of its three components: creation; preservation; destruction (and rebirth). The chanting of this mantra heralds our universality, which is why we usually chant Om before and/or after meditation and yoga practice, and when we read sacred, ancient texts. By repeating a vibration or sound over and over, it will become part of your physiology; it will become your mind; it will become *you. * It will lose all meaning, all definition, and all relevance. There will be no separation between you and the vibration that is resonating right now.
Chanting Om (out loud or silently) is an ideal reminder of our universality.
